Basically, this booklet contains two parts: operation guidance and
related valuable information.
In the first part of the operation guidance, we will provide you with
detailed illustrations and descriptions, so you will gain operational
knowledge of your printer quicker and easier than ever before.
In the latter chapters of the manual there are chapters on
Trouble Shooting and general Maintenance, as well as
Reference Technical information.
We hope you enjoy reading your manual and have many
years of good reliable use with your printer!
You are advised to check first for the possible shipping damage.
There are two ways you can do it:
1. Inspect the outer appearances of both the box and the printer for
possible damage.
2. Raise the top cover of the printer to see if the media
compartments are in order.
If damages did occur, immediately file the claim to the shipping
company for settlement.
Having performed the primary inspections.
Please check whether you have received the following accessories

7. Performing Calibration
1. Hold down the feed button while turning on the power, until the
printing motor becomes activated.
2. The calibration has been performed while the printer
automatically feed label stock for certain length.
Note:
This step is very important and must always be carried
out whenever media is being changed. Failure to do so
will result in miss-detection of the label sensor.

8. Printing Configuration Report
1. Hold down the feed button while turning on the power, until the
printing motor becomes activated.
2. After feeding 12-inch blank media, the printing motor will
suspend for one second, then it will print out the configuration
profile. This profile states the firmware version, ROM checksum,
RS232, thermal transfer/direct thermal settings, hardware
configuration and font types.
3. With PPLB emulation, the printer will enter character dump
mode. To exit from dump mode, just re-start the printer again.
9. Reset the Printer to Factory Default
1. Turn on the printer and wait for 5 or more seconds.
2. Press the feed button for about 10 seconds; the ready indicator
and the power indicator will then go off in order.
3. While both indicators are lit again, release the feed button.
4. At this point, the printer will begin to feed the label stock for
approximately 12 inches in length, and return to the factory
default settings.
Note :
All settings are stored in non-volatile E2PROM and
cannot be destroyed even turn off the printer.

10. Connecting the Printer and Computer
Note :
The power supply barrel connector must be inserted into the
power jack on the back of the printer before connecting the
communication cables.
The 9742 printer is equipped with a ninepin Electronics Industries
Association (EIA) RS-232 serial data interface, a standard
Centronics parallel interface and USB interface.
In either case, you must supply the required interface cable for
your application!
Note :
This printer complies with FCC "Rules and Regulations" , Part
15, for Class A Equipment, using fully shielded six-foot data
cables. Use of longer cables or unshielded cables may
increase radiated emissions above the Class A limits.
Serial (RS-232) Interface Requirements
The required cable must have a nine-pin "D" type male connector
on one end, which is plugged into the mating serial port located on
the back of the printer. The other end of this signal interface cable
connects to a serial port at the host computer.
For technical and pin-out information, please refer to the
Reference Technical Information-Interface Specification on page
55 of this booklet.

RS232 Serial Port
Parallel Port
34
35
Page 19
MO9740 Manual
MO9740 Manual
Parallel Interface Requirements
The required cable (IEEE 1284-compliant is recommended) must
have a standard 36-pin parallel connector on one end, which is
plugged into the parallel port located on the back of the printer. The
other end of the parallel interface cable connects to the printer
connector at the host computer. For pin-out information, refer to
the Reference Technical Information- Interface Specification.
Serial and Parallel Cabling Requirements.
Data cables must be of fully shielded construction and fitted with
metal or metalized connector shells. This will help to prevent
radiation and reception of electrical noise.
To minimize electrical noise pickup in the cable:
■Keep data cables as short as possible
■Do not tightly bundle the data cables with power cords.
■Do not tie the data cables to power wire conduits.
Notes :
1. Using Centronics allows for a much higher speed
communication than the use of a serial.
2. It is not necessary to set the switch or send any command
to select the parallel or serial port. The printer can
automatically detect it.
3. The default settings can be read from the configuration report
11. Communicating with the Printer
The bundled printer driver can be applied to all the applications
under Windows 98/ME/2000/XP, and Windows NT. Through this
driver you may run any popular software applications e.g.
MS-Word and print out the contents by this label printer as long as
they are for Windows.
Before installation
1. Check the contents of the driver to ensure it is complete.
2. Make a backup copy of this driver.
3. Read the read.txt file for installation guide and change notices.

D. Miscellaneous
The host shows "Printer Time out"
1. Check if the communication cable(parallel, serial or USB) is
connected securely to your parallel or serial port on the PC and to
the connector on the printer at the other end.
2. Check if the printer power is turned on.
If the power cord is connected, the power switch is at position "I" and
the power LED has still not illuminated, check the fuse inside the power
adapter case.
The data has been sent, but there is no output from the printer. Check
the active printer driver, if Label Dr. for your Windows system and the
label printer has been selected.
Vertical streaks in the printout usually indicate a dirty or faulty print
head.(Refer to the following example)
Clean the print head first, if they still persist, replace the print head.
Poor printout quality.
. The ribbon may not be qualified.
. The media may not be qualified.
. Adjust the Darkness(heat temperature).
. Slow down the print speed.
. Refer to the next chapter and clean the related spare parts.
Recovery
To continue your print jobs after the abnormal conditions have been
corrected, simply press the panel button or restart the printer. Make sure
that the LED is not blinking and remember to resend your files
.

13. Caring for Your Printer
Clean the following areas of the printer after 8 rolls of label stocks
have been used. In each case, use a cotton bud dampened with
alcohol. Do not soak the cotton bud excessively.
Note :
Always switch off the power before cleaning.
Cleaning
Thermal Print Head
Thermal paper stock and ribbon will release debris on the print
head and degrade printing quality. Clean the print head with
methanol or isopropyl alcohol with a cotton bud. Do not touch the
heater element with your fingers. Debris or dirt on the roller
should be cleaned with alcohol.
Paper Sensor
Debris or dirt on the paper sensor will cause a miss-read or
unstable detection of the label gap. Clean with a cotton bud
dampened with alcohol.
Replacing Thermal Print Head
1. Switch off the power and wait for both LEDs to go off.
2. Push print head module and pull it down as the 2 arrows shown
to release print head module from printer chassis.

module (12, 13).
4. Unplug the 2 print head cables from the connectors on print head
to take off the old print head.
5. Plug the 2 print head cables into the new print head.
6. Screw the new print head onto print head module (12,13).
7. Put the new print head module back onto the printer chassis in
the same way, which you released it from printer chassis.

2. Since this printer uses band buffer technology, if you just
print texts or barcodes the maximum length can be more
than 30 inches, whereas if you print many graphics the
maximum length can only be few inches under standard
